SCREEN.

Specification of Letters Patent.

Patented Mar. 9, 1920.

Application-filed October 25, 1917. Serial No. 198,424.

7 '0 all whom it may concern:

Be it known that I, LUoY A. STONEMAN, a citizen of the United States, residing at Columbia, in the county of Fluvanna and State of Virginia, have invented certain new and useful Improvements in Screens, of which the following is a specification.

This invention relates to improvements in screens and it is the principal object of the invention to provide a screen capable of being arranged in windows of buildings in a manner to permit free or uninterrupted movement of the window sashes therein and also, to allow opening and closing of the screen as it may be desired.

It is a more specific object of the invention to provide a device of the character mentioned including a main frame adapted to be fitted into a window frame having a plurality of screens slidably mountedtherein, the said screens being independent of each other.

The improvements in the details and arrangement of parts will be apparent from an inspection of the accompanying drawings, in connection with the specific description hereinafter contained, and wherein the preferred embodiment of the invention is disclosed for the purpose of imparting a full, understanding of the same.

In the drawings Figure 1 is a front elevation of the device;

Fig. 2 is a fragmentary section; and

Fig. 3 is a fragmentary longitudinal section.

Fig. 4 is a fragmentary sectional view through the upper and lower screens.

Having more particular reference to the drawings and in connection with which like reference characters will refer to corresponding parts throughout the several views of the drawings, 1 represents the main frame of the improved device in its entirety, the said frame being formed substantially rectangular in shape and constructed of sheet metal. The frame 1 includes an outer or body portion 3 for engagement within a window frame F, the turned back portions 3 and the inwardly extending spaced guide flanges 2. Openings 4 may be and preferably are formed in the outer portions 3 and 3 and, obviously, will permit the passing of screws or like fastening devices therethrough into engagement with the window frame, which I shall designate for the purpose of convenience by. the reference letter F.

Slidably mounted in the channel between the flange 2 of the frame 1 are upper and lower screen carrying frames 5, which screens, as will be noted, when moved to their closed positions have the upper and lower marginal edges or meeting rail portions thereof overlapping, while theside edges of the screen frame are received between the guide flanges 2, thereby forming a complete closure. Interengageable and oppositely directed flanges 5 are formed upon the adjacent edges of the frames 5 and serve to prevent insects from crawling between the same when closed.

'The members 5 are bent into U shape a transversely and reversely attached upon the confronting faces of the meeting rail portions of the screen frame, and interlock when the screen frames are in closed position.-

Mounted upon a pin 6 secured to one side of the frame 1 is a hook 7, which hook is adapted to be engaged with the lower marginal edge of the upper screen carrying frame 5, thereby serving as means for maintaining the same in its raised position.

By so arranging the frame 1 in the window frame F it will be readily understood that the upper and lOWer screen carrying frames 5 may be freely moved to open or closed osition without interfering in any way with the operation of the window sashes. Of course, to lower the upper screen carrying frame it is necessary to disengage the hook 7 from the lower marginal edge thereof.

It is to be understood, that my improved screen may be constructed in varying sizes, in order that the same may be arranged or fitted to window frames differing in size. The frame 1 may be readily removed in win- 'ter time or in fact, whenever it is so desired without mutilating or damaging the window frame to any material extent.

Manifestly, the construction shown is capable of considerable modification and such modification as is within the scope of my claims, I consider within the spirit of my invention.

I claim 1. In a device of the class described a combined support and guide formed from a strip of material folded intermediate the edges toward a medial line to form a base and laterall directed-attaching flanges and the inwar ly folded portions further bent intermediate their edges substantially at right angles to the base to form screen frame guide elements in spaced relations, said base adapted to bear against a supporting body and connected thereto by attaching means operating through the attaching flanges externally of the guide elements.

2. In a device of the class described, coacting screen frames slidably arranged relative to each other and including meeting rail members and strips bent into U shape transversely and reversely attached upon the confronting faces of said meetingrails, said strips adapted to interlock when the frames are in closed position.

In testimony whereof I afiix my signature hereto.

LUCY A. STQNEMAN.
